When you look at https://berniesanders.com/issues/racial-justice/ and you do a search for "African-American" (it's hyphenated on the site so yeah - I'm doing it too for coverage) you get 16 matches.
For "Latino" you get 11 matches.
Guess how many times the variation of "Asian" or "AAPI" as in "Asian American" is found?
Here - I'll give you a hint.
